Support accessibility shorcut secondary action (3/n)

Combine the UI with both shortcut preference and edit dialog.

This CL only contains UI and related connections.
Related logic implementation will be added in next CL.

Since the drawable resources are not ready, put the mock
drawables as temporary. Once the drawbles are provided by UX,
create a CL to replace the related resources.
